Solve x2 + 6x = 7 by completing the square. which is the solution set of the equation?

x = 1; x = -7

Step-by-step explanation:

Given  

x^2 + 6x = 7  

we want to complete the square. If we have (x + a)^2 and expand it we get: x^2 + 2ax + a^2. The second term in the equation suggest that 2ax = 6x or a = 3. Then, adding 3^2 at both sides of the equation of the problem:

x^2 + 6x + 3^2 = 7 + 3^2

(x + 3)^2 = 16

x + 3 = sqrt(16)

That gives us two  options

x + 3 = 4

x = 1

or

x + 3 = -4

x = -7

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
